`To all whom 'it may concern:

Be it -known that I, WILLIAM W. Hor- Kms, a citizen of the UnitedStates, residing at St. Louis, Missouri, have invented a certain new anduseful Improvement in Davenports, of 'which vthe following is `a full,clear, and exact description, such as will enable 'others skilled intheart to lwhich it ap- .pertains to make and use the same, reference beinghad to the accompanying drawings, forming part of this specification, inwhich- Y Y Figure 1 is an elevational view of m improved davenport, thenear side wall eing removed to more clearly show the construction of themoving parts. Fig. Q is a similar view showing the parts in changedpositions. Fig. 3 is a similar view showing the prarts in still anotherposition. Fig. ltis a ont elevational view showing the parts in theposition illustrated in Fig. 1, the middle i portion of the davenportbeing broken away.

This invention relates to a newxand useful improvement in foldingldavenports of that character wherein the seat portion can beA foldedover and the back portion folded down, so that a bed maybe formed, saidporositively connected together, and' constituting what is known as aone movement reversible davenport.V The under side of the seat portionand the rear side of the back portion are provided vwith mattresses,such for instance, as woven wire mattresses, so that whenthe parts aremoved in to' position to forma bed, the mattresses w1ll e uppermost.VrIhe opposite faces of the seat and'back port-ions are upholstered inthe usual way, so that lwhen, the partsl are- -in theposition showninFig. 1, andthe device used as a davenport, 'the upholstered portionswill be in use. A In the drawing there are two end walls V 1, connectedyby a bottom wall 2, and front and back rails 3, said bottom wall andrails.

forming a trough or box in which bedclothes, pillows and the like may bekept. The end walls maybe connected by a back wall or tie-rod ifdesired, but this is not essential. 4 and 5 are bearing plates securedto the end framel into which are trunnioned the seat and back frames 6and 7 respectively, the trunnions being held in position by hooks 4a and5a as shown, said hooks preventing the trunnions being lifted out of thebearing plates when the parts are in the position toform a davenport asshown in Fig. 1. The free edge of the seat portion is supported by aprojection 7a extending 'fromthe back frame. To this projection is'secured a spring 8 for counterbalancing the ak when the same is swungdown upon a 9 isan l.shaped link pivot-ally connected to the end platesof the seat and back frames, there being a link at each end of thedavenort. p Indescribing the operation of this link, l will assume thatthe dotted line a-b indicates the axial line of the seat portion, whilethe line c-d indicates the axial line of the back portion. The pivialpoint of connection of the link 9 to the s at portion, is below theaxial line a-b as shown in Fig. 1, so that when the strap 10 connectedwith the free edge of the seat portion is grasped to lift the seat asshown by dotted line in Fig. 1,

said pivotal point moves in the are of a cirl cle indicated by the linee, and as the pivotal point of connection of the link 9 to the backportion moves in the arc of.a circle indicated by the line f, the backportion is caused to be tilted to the rea-r as shown by the dottedlilies. This is a desirable feature of my invention and follows from thefixed relation of the pivotal points of link 9.to each other. By tiltingthe back portion rearwardly, the upholstering thereon is not rubbed bythe upward movement of the free edge of the seat portion. In theopposite movementbf tlie'parts,.when the seat is being restored home,the back portion is tilted rearwardly to admit of the downward movenientof the seat, and when the seat is home,

the link 9 draws it forwardly so as to cause the upholstering to Afitover the seat snugly. The 'link 9 holds the back firmly in its verticalposition. ln addition to the act-ion of the `link 9, the free edge ofthe seat engages the stops 7a and tends to tilt the back portionforwardly.

W'hen the seat portion is lifted to the positio'n in Fig. 2, access ishad to the box thereunder, which,'las before described, may be used forthe storage of bed-clothes, pillows, etc., when not inuse. Furthermovement of the seat portion causes the parts to assume the positionshown in Fig. 3 in which position, a pivoted leg 11 swings downwardly tosupport theI free edge of the sea-t. When theA seat portion reaches avhorizontal position, that is, when the leg 11 1s on the ioor, thepivotal point of link 9 to the seat portion becomes av fixed point orulcrum. The trunnion or pivotal point of support of the back portion isalso fixed.

The pivotal pointof connection of link 9 -to the 'back portion'ismovable, and in order Ito prevent the back portion from slamtionoccupied by the back portion'when thev seat portion is extendedoutwardly, and rests upon its leg 11. In this osition the dotted lineg--t indicates thev ine of centers between the two fixed fulcrumsto-wit; the pivotal point of connection between the link 9 and the seatportion, and pivotal point of the back portion.

Swinging from the irst mentioned lixed fulcrum, the movable pivotalpoints of connection between link 9 and the back ortion,

y tends to move in the arc of a circ e indicated by the line d, whilethe same movable pivotal point swing-ing in the arc of a circle 7,described from the second mentioned` pivotal point to-wit; the pivotalypoint of the back portion. The rigidity of the end frame of the backportion will cause. the pivotal point to move in the arc of a clrcledescribed by the line j, while the link 9 will be strained in its effortto follow the line z', the link 9 thus acting as a spring and beingunder compressionuntil the line g--al is passed, when the sprin in link9 restores the link r'to normal, an tends to hold the back portion down.'This snap of the toggle is preferably)7 caused by a yielding link 9Abut it is o vious that lost motion could be provided at the pivotalpoints in which event link 9 could berigid. When the parts are worn,lost motion thereof, will detract from the spring action of link 9.

In the position of the 1t is impossible to raisethe seat portion bylifting itl at the free edge thereof, because to do so would place thelink 9 in com ression-the arcs of movement described, rom

the pivotal point of the seat and the pivotal point of connectionbetween link 9 and the back portion, being diierent. It is thereforenecessary to llft the front edge of the lback ortion by means of a strap13 breakin t e to ejoint which has acted as a lox to hoIfIthe seat andback frames .in horizontalNalin'ement. A

IWhen theback portion lies in its horizontal position, the spring 8 isunder tension, and acts as a counterbalance. The free edge ofthe backportion issupported in its horizontal position by the pin 14, whichrests parts shown in Fig. 3

on the top of a post 15, as shown in Fig. 3. This post 15 also coperateswith thc end of link 9 when the seat portion assumes its horizontalposition. v

l16 indicates a lever pivotally mounted on the end framing of thedavenport, there being preferably a lever at each end of the davenport,the lower end of said lever projecting outwardly slightly beyond the endof the davenport, and the upper end terminating under a pin 16a on theend frame of the back portion when in its horizontal position. A spring.16b holds the lower end of the lever up. This lever enables the operatorto break the toggle and lift the back portion upwardly to the positionshown by dotted lines in Fig. 3, without necessitating the use ofthestraps 13. When-the back portion is raised to the position shown indotted' lines,l where it is sustained by the links 9, the operator canthen lift the back .portion to its vert-ical position by reversing theseat portion. Thus it is unnecessary by the use of the lever 16 toattach the back -portion in changing from a bed to a davenport.

I claim:

'1. In a davenport, a supporting frame, seat and back portions'pivotally mounted therein, and' a link connected tothe back portion infront of its center line, and to said seat portion below its centerline, when the parts are in position to form a davenport,-whcreby saidseat and back portions are alternately placed in control of each otherin changing from a davenport to a bed and vice versa.

2. In a davenport, a 4supporting frame, scat and back portions pivotallysupported thereby, and a inkconnecting said portions in such manner thatwhen the seat portion is lifted to be swung upwardly and outwardly, theback portion is caused to be tilted rearwardly, wardly by said link.

. 3. In a davenport, a supporting frame, seat and back ortions pivotallymounted `therein, means or of said seat portion when in its outerposition, means for supporting the free edge position, and a linkpivotally connected 'to said seat and back' portions at relatively fixedpivotal points, the oint of attachment of said link to said-back ortionbeing below the line of centers of t e pivotal points ofv said seat andback ortions when said parts are in horizontal aIineinent.

4. In a davenport, the combination of the supporting -frame, back andseat portions plvotall arranged therein, a link connecting sal portions,whereby when the parts are in a position to form a daven ort, the reared of the v'seat may be li swung orwardly and outwardly, the .piv-

and then swungA forsupporting the free edge d and v 1lb of saidv backportion when 1n its horizontal i tilt backwa'rdly before swingingforwardly to a horizont-al position, and counterbalaneng devicesfor saidparts.

5. In a one movement reversible davenport, a supporting frame, seat andback portions pivotally mounted therein, and a link connecting saidportions whereby in moving the parts to form a bed, the seat constitutesthe operating medium for the back portion, tilting the same rearwardlybefore moving it forwardly, and when moving said parts to form adavenport, the back portion consti-I tutes the operating medium for theseat.

6. In a davenport, pivotally mounted seat and back portions, a linkconnecting said portions and serving to lock them -in horizontalalinement, anda foot lever coperating with the back portion to raiseitto a position where it can be operated by the seat portion through themediumof said link.

In testimony whereof I hereunto aiX my signature in the resence of twowitnesses, this 16th day of ctober, 1909.
